Sludge Flakes in Central Heating Systems with plastic pipes
Sludge flakes form when regular sludge hardens into rigid pieces, larger than the typical mud-like consistency. These flakes can easily block boilers, pumps, and radiators, causing significant central heating issues. Even if the water appears clear, a system can still be clogged with sludge flakes, which is a common cause of breakdowns.
Common Signs of Sludge Flakes:
- Clear system water despite no cleaning.
- Radiators fail intermittently, eventually stopping.
- Boilers shut down regularly.
- Recurring pump failures.
A standard power flush is often ineffective in removing these flakes, as they resist being dislodged. For better results, specialist techniques, like powder flushing, are needed. Most regular plumbers might not recognize this issue, and specialized professionals should be consulted for accurate diagnosis and cleaning.
Testing for Sludge Flakes:
- Take two water samples from the system. If the water is clear and you notice flakes settling at the bottom, sludge flakes are present.
Recommended Action:
If you suspect sludge flakes in your system, it’s essential to contact a specialist who understands this condition. A combination of a professional flush and part replacement may be necessary to prevent recurring issues.
